ABSTRACT

The invention relates to a domestic cooling appliance ( 1 ) having at least an interior ( 4 ), which is delimited by the walls of an inner container ( 3 ) and configured to receive food, and with a shelf ( 9 ), which is arranged in the interior ( 4 ), and with a food receiving unit, which is attached to the shelf ( 9 ) by means of a retaining device ( 15 ), wherein the retaining device ( 15 ) is size adjustable and in a first size adjustment configured to receive a first food receiving unit ( 14 ) having a first size and in a second size adjustment configured to receive a second food receiving unit ( 16 ) having a second size, which is different from the first size.

FIELD OF INVENTION

The invention relates to a domestic cooling appliance having at least aninterior, which is delimited by the walls of an inner container andwhich is configured to receive food. Besides, the domestic coolingappliance comprises a first shelf, which is arranged in the interior.Moreover, the domestic cooling appliance has a first food receivingunit, which is attached to the shelf by means of a retaining device.

PRIOR ART

It is known with regard to domestic cooling appliances that they usuallyfeature a plurality of shelves in an interior, by means of which theinterior is divided into partial volumes. Storage goods can bepositioned on the shelves. These storage goods are usually foodstuffs,i.e. food and beverages, which can thus be individually stored. Such ashelf usually features a plate-like element. Such a shelf is mounted onthe walls of the inner container and can preferably also be pulled outand slid in and also in particular completely removed.

In order to increase storage capacity, it is known for example from WO2014/090733 A1 that an additional receiving part for food is arranged atsuch a shelf. With such designs, where this additional receiving part isarranged at the shelf beneath said shelf, mounting at the shelf iscumbersome and, besides, minimized with regard to the creation ofvariants. A pivoting of a bracket of the receiving part itself can beperformed.

PURPOSE OF THE INVENTION

It is the object of the present invention to provide a domestic coolingappliance where the food storage capacity of a module with a shelf and afurther receiving part for storing food attached thereto is morevariable.

This object is solved by a domestic cooling appliance having thefeatures of claim 1.

A domestic cooling appliance according to the invention comprises atleast an interior for receiving food, which is delimited by the walls ofan inner container of the domestic cooling appliance. The domesticcooling appliance comprises at least one shelf, which is arranged in theinterior. Besides, the domestic cooling appliance comprises a foodreceiving unit which is attached to the first shelf by means of aretaining device which is separate from the food receiving unit. Anessential idea of the invention is to be seen in that the retainingdevice itself is size adjustable. In a first size adjustment of theretaining device said retaining device is configured to receive thefirst food receiving unit having a first size. A size adjustment of thisretaining device, which does not require additional components, resultsin the adjustment of a second size, in which the retaining device isconfigured to receive a second food receiving unit having a second size,which is different from the first size. Thus, the retaining device canbe mechanically adjusted in itself, which presently results in a sizevariation. Due to this variability, the module with the shelf and a foodreceiving unit is rendered variable and flexible such that differentlysized food receiving units can be arranged at the shelf.

The first food receiving unit is in particular a unit that is inherentlyrigid, dimensionally stable and unalterable with regard to its capacity.It is not in itself deformable. Thus, the storage capacity of a foodreceiving unit is unalterable. The same in particular also applies tothe second food receiving unit.

Thus, the invention is particularly advantageous in that according todemand differently sized food receiving units can be attached to theshelf and thus differently sized additional volumes for the reception offood provided. Thus, the amount of food which can be received by amodule formed by the first shelf and a food receiving unit can beindividually increased or reduced. Moreover, due to the size variabilityof the module, in particular due to the attachment of a larger foodreceiving unit or a smaller food receiving unit to the shelf, thestorage capacity of the entire module can be adjusted to the size of aspecifically to be stored storage item. As a result, there is nounnecessary waste of storage space, while on the other hand the storagecapacity is not undesirably restricted either.

As a result of such a design, also the interior can be improved andoptimally utilized with regard to its storage capacity.

When the retaining device is adjusted in its size, the shelf remainsunaltered with regard to its position and size. The first and the secondfood receiving unit also remain unchanged in their respective sizes. Inparticular, during the size adjustment of the retaining device no foodreceiving unit is arranged at the retaining device. Only after thedesired size of the retaining device has been adjusted, the foodreceiving unit provided for this size adjustment is mounted thereon, inparticular not until then inserted into a size adjusted receiving spaceof the retaining device and held by the retaining device.

It is preferably provided that the retaining device has a first carrierand a second carrier. On these two carriers the first food receivingunit or the second food receiving unit, depending on which of them isarranged at the retaining device, is mounted or arranged movably withregard to said carriers.

By means of the retaining device it is provided that only one foodreceiving unit at a time can be retained. However, by means of theinvention it is enabled that said respective food receiving unit, whichis attached to the shelf and retained by the retaining device, can bedifferently sized.

This food receiving unit which is attached to the shelf by means of theretaining device can be displaced relative to the carriers in a straightline in one direction, in particular in the depth direction of thedomestic cooling appliance pulled out of or slid into the interior. Thusit is also easy to use and easily accessible with regard to theinsertion or removal of food.

It is in particular provided that the direction of movement of a foodreceiving unit which is arranged at the two carriers is perpendicular tothe direction in which the retaining device is adjustable with regard toits size.

It is in particular provided that a food receiving unit and thus thefirst food receiving unit or the second food receiving unit is arrangedbeneath the shelf and retained by the retaining device. Thus, on itsupper side the shelf is not restricted with regard to its capacity.

Besides, as a result of such a design and local arrangement the foodreceiving unit is covered by the shelf. Due to the fact that a foodreceiving unit is as it were suspended from the shelf from below bymeans of the retaining device, also the package space of the interiorbeneath the shelf is optimally utilized. Thus, a food receiving unitwhich is attached to a shelf by means of the retaining device is alsoimproved as regards ease of handling.

The two carriers can preferably be formed in the manner of rails orprofiles and can be profile parts.

In a preferred embodiment, it is envisaged that the first carrier isimmovably arranged at the shelf. Thus a relative movement of said firstcarrier with regard to the shelf, particularly in order to adjust thesize of the retaining device, is not envisaged. Thus, a mechanicallyhighly stable design of the retaining device is achieved and themounting of a food receiving unit on the first carrier improved.

It is preferably provided that for the size adjustment of the retainingdevice the second carrier is movable with regard to the shelf andcorrespondingly arranged at the shelf. Thus, a very simple design iscreated in order to be able to change or adjust the retaining device inits size. Particularly if the first carrier is immovably arranged at theshelf, the size adjustment can be safely and precisely performed withoutthe occurrence of undesired size tolerances and without impairment ofthe reception or mounting of a food receiving unit on the carriers.

Due to the fact that only one of the carriers, i.e. in particular thesecond carrier, is formed to be movable relative to the shelf, asimultaneous adjustment of both carriers with regard to their positionis also prevented. The practicality of the adjustment for a user is thusimproved and more easily comprehensible. It is in particular providedthat for the size adjustment the retaining device is formed in discretesize levels. This is advantageous in that the exactness of the sizeadjustment is improved. Due to the fact that these size levels arealready predefined, in particular simply through the design of theretaining device itself, it is very easy for a user to identify therespective size levels and then to exactly adjust the desired sizelevel. Thus, the subsequent placement of a food receiving unit is alsosimplified, since the size adjustment of the retaining device hasalready been precisely performed in adaptation, as it were, to therespective size of the food receiving unit to be inserted. An extensivere-setting or readjustment of the size of the retaining device is thusprevented, which might occur in the case of a continually sizeadjustable retaining device.

In particular, the size levels are adjusted to the given sizes of thefirst food receiving unit and of the second food receiving unit. Inparticular, if the food receiving units which are provided for mountingto the shelf feature conventional, in particular standardised sizes,this adjustment of discrete size levels of the retaining device is thenparticularly advantageous. In that case, a design of the retainingdevice with the discrete size levels is already given, which is adjustedto these predefined sizes of the food receiving units. Thereby, theabove-mentioned advantages are again reinforced.

It is preferably provided that the retaining device features a latchingelement. A latching unit is in particular formed at the shelf, whichfeatures a first latching reception and at least a second latchingreception. The latching element engages into the first latchingreception in order to adjust the individual size of the retaining deviceand to fixate a first size of the retaining device thus adjusted.Besides, in order to adjust and fixate a second size of the retainingdevice, the latching element engages into the second latching reception.Thus, these two different possible size levels of the retaining devices,which are formed and capable of being adjusted by the latchingreceptions and the latching element, are very easily adjustable.Moreover, they are retained in a mechanically safe manner and anundesired release is avoided. Besides, such a design with a latchingelement and a latching unit is also mechanically highly stressable.

It is preferably provided that the latching element has at least a firstlatching tooth and a second latching tooth. Due to the provision of suchan at least duplicate and thus redundant design of the latching elementwith these latching teeth, mechanical coupling with the latching unitcan be improved. The stability and fixation of the individually selectedsize level of the retaining device is thus safely maintained without theoccurrence of undesired tolerances.

It can be provided that the first latching reception and the secondlatching reception form a toothed rack. This structure enables a simpledesign of the latching unit. Besides, the direction of adjustment forthe size adjustment of the retaining device is predefined in a simplemanner since, based on the linear toothed rack, this direction ofadjustment is also linear. This results in a simple size adjustment ofthe retaining device without jamming.

It is advantageously provided that the latched or interlocked statebetween the latching element and the first latching reception or thesecond latching reception is maintained in prestressed condition bymeans of a spring element of the retaining device. This is particularlyadvantageous in that thus an undesired release of the latched state ispreventable in a further enhanced manner by means of the prestressingforce of the spring element. In this context, with its prestressingforce the spring element acts in a direction which as it were attemptsto push the latching element away from the opposite carrier so that bymeans of the spring element with its spring force the latching elementis as it were pushed away from the stationary first carrier.

It is in particular provided that an operating element is arranged atthe second carrier, operation of which enables the disengagement of thelatching element from the first latching reception or the secondlatching reception and thus an alteration of the adjusted and fixatedsize adjustment of the retaining device. Thus, a very easy anduser-friendly operating mechanism for the size adjustment of theretaining device can be provided. In this context, the operating elementis easy to operate for a user and preferably has to be moved,particularly pushed, only in one direction. As a result of this mannerof operation of the operating element also a reliable and simple releaseof the latched state is achievable. Due to this design of the retainingdevice a reliable principle with regard to the size adjustment of theretaining device can be achieved with a minimum number of components andin addition, as it were via a small and short-range effect chain of thecomponents involved, an adjustment of a specific size of the retainingis enabled that is highly play-free and thus features low tolerances.

It is advantageously provided that the spring element is coupled to theoperating element such and through operation of the operating elementthe spring element is operated such that the prestressed state of thelatching element in the first latching reception or the prestressedstate of the latching element in the second latching reception isreleased and the latching element is removed from the first latchingreception or the second reception and lowered into the operatingelement. In this context, this means that through operation of theoperating element with the spring element the latching element isautomatically removed from the tooth structure of the latching unit andthe latching element is then inserted into the operating element. Thesize adjustment of the retaining device is consequently enabled in avery simple and space-saving manner since in this context a distancebetween the operating element and the latching unit can thus be minimal.For, in the disengaged and thus decoupled state between the latchingelement and the latching unit, the latching element is, as it were, nolonger present since it is arranged in the operating element. It thusdoes not impede a relative movement between the operating element, whichis preferably arranged at the movable second carrier, and the latchingunit, which is in particular immovably arranged at the shelf. As aresult, also a very rapid adjustment of the different sizes of theretaining device is enabled.

Besides, during the size adjustment of the retaining device and thusalso during the movement of the operating element with the latchingelement relative to the latching unit, the latching element is thus notdamaged. This ensures permanent high functionality of the latchingelement.

It is preferably provided that the shelf features a plate and a framewhich at least partially surrounds the plate. The latching unit is inparticular formed in the frame. The plate can, for example, be made ofglass or plastic. The plate can be at least partially transparent. Theplate is protected by the frame. In this context, the frame can beprovided for direct mechanical coupling to other components, inparticular for mounting on supports on the walls of the inner container.Thus, the plate is not directly contacted and protected from undesirablewear and damage.

Preferably, the frame features frame parts which encompass the plate onits edge sides.

Specifically, in two opposite frame parts recesses are formed, inparticular grooves, into which, respectively, the first carrier and thesecond carrier of the retaining device engage and wherein they aresupported. Thus, mounting of these two carriers is enabled in a highlystable manner and the plate is not impaired thereby. In an advantageousembodiment it is then envisaged that the second carrier of the retainingdevice, which is in particular movable relative to the shelf, is guidedin these grooves in the opposite frame parts and accordingly capable ofbeing moved therein.

The second carrier is thus prevented from undesirably falling out. It isin particular provided that the latching unit, in particular a latchingunit formed as a toothed rack, is formed in at least one of thesegrooves of a frame part. This latching unit can then be formed on agroove bottom or on a groove side wall. The latching unit can in thiscontext be integrated into the respective frame part.

Due to this local arrangement of the latching unit, the coupling to thelatching element can be improved and also maintained in a permanentlyprecise manner. Also, undesired decoupling between the latching elementand the latching unit is thus prevented. Besides, due to this design,also the precise displacement of the second carrier is enabled and thusalso the rapid, reliable and targeted attainment of a desired furthersize level of the retaining device.

It is preferably provided that the size adjustability is constituted bya width adjustment of a receiving space of the retaining device, whereinthe receiving space is formed to receive the first or the second foodreceiving unit.

It is preferably provided that by means of the retaining device thefirst food receiving unit and the second food receiving unit areretained at the shelf beneath said shelf, as explained above.

In an advantageous embodiment it is provided that the first foodreceiving unit is a trough or a bottle holder.

The second food receiving unit can be formed correspondingly.

DETAILED DESCRIPTION OF THE INVENTION

In the figures identical or functionally identical elements bear thesame reference numbers.

FIG. 1 shows in a perspective view a domestic cooling appliance (1). Thedomestic cooling appliance (1) can, for example, be a refrigerator or afreezer or a fridge-freezer. The domestic cooling appliance (1) isconfigured to receive foodstuffs such as food or beverages. Thesefoodstuffs are thus storage goods which can be inserted into thedomestic cooling appliance (1) for storing and preserving.

The domestic cooling appliance (1) comprises a housing (2), in which aninner container (3) is arranged. With its walls, which are constitutedby two opposite vertical side walls, a rear wall, a bottom wall and atop wall, the inner container (3) delimits an interior (4).

In the interior (4) an arrangement of a plurality of drawers is shown,which is merely intended as an example, wherein presently a first drawer(5) and a second drawer (6) are indicated with reference signs, againmerely by way of example.

The interior (4) can be closed by a door (7), which is pivotablyarranged at the housing (2). A plurality of door racks are arranged onan inner side facing the interior (4), of which a first door rack (8) isindicated by a reference sign.

Besides, in the interior (4) at least one shelf (9) is arranged. Theshelf (9) divides the interior (4) into partial volumes. As can be seen,this shelf (9) extends across the whole width (width direction inx-direction). The shelf (9) comprises a plate (10), which can, forexample, be made of glass. Besides, the shelf (9) comprises a frame (11)which surrounds the plate (10).

In the embodiment, the shelf (9) is non-destructively detachablyremovable from the interior and mounted on supports of the innercontainer (3), which are not shown.

On an upper side (12) of the shelf (9) and in particular of the plate(10) foodstuffs can be positioned as storage goods.

As can also already be seen in FIG. 1 and as schematically shown, on anunderside (13) opposite the upper side (12) and thus beneath the shelf(9) a first food receiving unit (14) is arranged. In the embodiment,this first food receiving (14) unit is a trough which is configured toreceive foodstuffs. However, the first food receiving unit (14) canalso, for example, be a bottle holder.

The first food receiving unit (14) can be pulled out and slid in in thedepth direction and thus in the z direction of the domestic coolingappliance (1) and in this context moved relative to the shelf (9), whichis immovably arranged in the interior (4). Thus, accessibility fromabove into the first food receiving unit (14) in its pulled out state isenabled. In its fully inserted state, as shown in FIG. 1, the first foodreceiving unit (14) is covered from above by the shelf (9), inparticular the plate (10).

A module is formed by the shelf (9) and the first food receiving unit(14), which offers a plurality of options and diverse places for thereception of food.

FIG. 2 shows in a front view the first embodiment of such a module. Inthis embodiment it can be seen that the first food receiving unit (14)is retained at the shelf (9) by a retaining device (15). The first foodreceiving unit (14) has an individual and unalterable size, which ischaracterized by a specific width in the x direction.

The retaining device (15) is formed such that it is size adjustable initself. This means in the embodiment that the retaining device (15) issize adjustable in the width direction and thus in the x direction. Dueto this size variability of the retaining device (15), the reception ofdifferently sized food receiving units can be enabled.

In this context FIG. 3 shows a front view, in which by means of theretaining device (15) a second food receiving unit (16) is attachable tothe shelf (9) previously shown in FIG. 2. As can be seen in comparisonwith FIG. 2, this second food receiving unit (16) is smaller than thefirst food receiving unit (14), in particular smaller with regard to itswidth. Due to the adjustability of the retaining device (15),alternatively two differently sized food receiving units, i.e. at leastthe first food receiving unit (14) and the second food receiving unit(16) having a different size thereto, can be accommodated one at time atthe same shelf (9) by means of the same retaining device (15).

In particular, the retaining device (15) is thus adjustable with regardto a receiving space (17), in which the first food receiving unit (14)or the second food receiving unit (16) can be accommodated. In thiscontext, the width of the receiving space (17), which is measured in thex direction, can be varied.

In FIG. 4 the module with the arrangement of the shelf (9) and the firstfood receiving unit (14) is shown in a perspective view. It can be seenthat presently the frame (11) has four frame parts, namely a first framepart (18), a second frame part (19), a third frame part (20) and afourth frame part (21).

FIG. 5 shows the embodiment according to FIG. 4 in a perspective viewwhich differs from FIG. 4.

As can particularly be gathered from FIG. 5, the retaining device (15)comprises a first separate carrier (22). This first carrier (22) is arail which extends between the first frame part (18) and the third framepart (20) and is preferably fastened thereto. This first carrier (22) ispreferably immovably mounted thereon so that it cannot move in relationthereto.

The retaining device (15) further comprises a second separate carrier(23). The second carrier (23) is preferably arranged parallel to thefirst carrier (22). The second carrier (23) is also preferably arrangedat the first frame part (18) and the third frame part (20). However, thesecond carrier (23) is arranged at the shelf (9) movably in relationthereto and it is specifically movable in a straight line in the widthdirection and thus in the x direction. Due to this design of the secondcarrier (23), the receiving space (17) can be adjusted and thus also thesize adjustment of the retaining device (15) altered.

As can already be seen from FIG. 2 to FIG. 4 and as shown in FIG. 5 inmore detail, the first food receiving unit (14) is movably retained atthe first carrier (22) and the second carrier (23) and can thus bepulled out and pushed in relative thereto in the depth direction andthus in the z direction.

As can further be seen in FIG. 5, the retaining device (15) comprises anoperating element (24), which is arranged at the second carrier (23).The size adjustment of the retaining device (15) can in particular beinitiated by pressing the operating element (24).

As shown with regard thereto in FIG. 6, in this embodiment the retainingdevice (15) has a spring element (25) which is coupled to the operatingelement (24). Besides, the retaining device (15) features a latchingelement (26) which according to the embodiment has a first latchingtooth (27), a second latching tooth (28) and a third latching tooth(29). These three latching teeth (27, 28 and 29) respectively engageinto a latching recess of a latching unit (33), which form a firstlatching reception (30). In dependence on the number of latching teethof the latching element (26), a latching reception can also comprise asmaller or larger number of latching recesses. By way of example, afirst latching recess (31) and a second latching recess (32) of thefirst latching reception (30) are indicated with reference signs. Thelatching unit (33) is formed at the shelf (9). It is in particularformed at the first frame part (18). In particular, this first framepart (18) features a groove (34) (FIG. 5) which is open to the insideand thus towards the opposite third frame part (20). In particular, thesecond carrier (23) engages into this groove (34) and is guided therein.

It is in particular also envisaged that a corresponding latching unit isformed in the opposite third frame part (20) and corresponding couplingis provided, as illustrated and explained in FIG. 6.

In FIG. 6 a first engaged state between the latching element (26) andthe latching unit (33) is formed, whereby also a first size of theretaining device (15) is adjusted. Thus, according to the illustrationof FIG. 6, also a first size level is realized. In this engaged state itis envisaged that the spring element (25) presses the latching element(26) into the latching unit (33) such that this interlocked or engagedstate is additionally stabilized. Therein, the prestressing forcegenerated by the spring element (25) acts outwards in the direction ofthe latching element (26) such that this latching element (26) ispressed as it were into the latching unit (33) at the first latchingreception (30).

At this first size level the first food receiving unit (14) can be heldby the retaining device (15).

In order to release the retaining device (15) and the adjusted sizelevel shown in FIG. 6, the operating element (24) is operated, inparticular pressed. Thus, the spring element (25) is acted on so that asa result of this impact the latching element (26) is then automaticallyremoved from the interlocked state with the latching unit (33), as shownbelow in FIG. 7.

It is moreover provided that the operating element (24), which is thenalso arranged in the second carrier (23) with a housing, is configuredto receive the latching element (26). As shown in FIG. 7, said latchingelement (26) is thus lowered into the second carrier (23) or into theoperating element (24). As a result, a change of position of the carrier(23) in relation to the shelf (9) is enabled in the x direction so thatin this respect a second size level can be adjusted, specifically areduction of the receiving space (17), so that subsequently for examplethe second food receiving unit (16) can be accommodated. Subsequent tothe attainment of this desired adjusted size level again a latchingbetween the latching element (26) and the latching unit (33) isperformed.

FIG. 7 further shows by way of example a second latching reception (36)with latching recesses into which the latching element (26) engages forthe adjustment of a second size level of the retaining device (15). Dueto the number of the latching teeth (27, 28, 29) of the latching element(26) formed in this embodiment, the second latching reception (36) ispresently also formed with three latching recesses, of which by way ofexample a first latching recess (37) and a second latching recess (38)of the second latching reception (36) are indicated with referencesigns.

As can be seen, the distance between the first latching reception (30)and the second latching reception (36) along the latching unit (33),which is formed by a toothed rack (39), can only be covered by adisplacement of the latching element (26) relative to the latching unit(33).

FIG. 8 shows an exemplary representation of an embodiment in which theoperating element (24) is shown in cross section from the opposite side.It can be provided that here a cam element (35) is present, which ismoved through operation of the operating element (24), wherein inconsequence of the movement of the cam element (35) the latching element(26) is raised or lowered and thus the coupled or decoupled state withthe latching unit (33) achieved.

It can be provided that here likewise a spring element (25) is presentand that the spring element (25) automatically enables the restorationof the operating element (24) into the basic state and/or effects theoperation of the cam element (35) in dependence on the operation of theoperating element (24).
